OFFICE FASTENER WITH LOCKABLE CAMMING HASP Albert J. Komenak, Stamford,Conn., assignor to The Excelsior Hardware Company, Stamford, Conn, acorporation of Connecticut Application June 26, 1941, Serial No. 399,827

11 Claims. (01. 70-76) This invention relates to lockable hasp fastenersof the typ in which the loop forming end of a U-shaped hasp swings toand from a position extending around and hugging the casing of its lockmechanism.

is disclosed in my copending application, Serial No. 349,339, inrelation to which the present improvements propose particularly to equipthe 5 A lockable hasp fastener of this general nature looped nose of thehasp with a combined lockable 1c depth of the case of the lock mechanismat the 20 front of the mounting or escutcheon plate in order that allparts of the lock may operate exclusively at the front of said plate andat the same time necessitate no increase in all-over depth of a fastenerwhere shallow proportions are highly desirable.

A further object is to embody-both the before mentioned locking means,and cam action or drawing-together means, in a single tongue of bentover formation which in the case of sheet 9 metal construction mayoriginate from the material that is removed from the sheet between thespaced arms of the U-shaped hasp.

A further object is so to form such tongue and so to cooperativelyrelate it to the shape of the lock case that this tongue shall becomequite inconspicuous or practically concealed when the hasp is closed.

A further object is to provide the before mentioned tongue with a.cam-like shape and dispo- 5 sition capabl of performing a camming actioncooperatively with the lock case and preferably throughout as large anangle of swinging movement of the hasp as is possible.

A still further object is to render the lock bolt virtually tamper-proofwhen it projects from its case in looking position by shielding the boltby means of the hasp and also by additional guard means flanking theextreme end of the bolt.

These and other Objects of the invention willc 'y appear from thefollowing description of one mechanical form of the present improvementsin which description reference is made to the accompanying drawing,wherein:

Referring to the drawing, the hinge abutment,

illustrated herein in the form of housing In, is provided with tongues(not shown) which penetrate its mounting plate [3 and are peened overagainst the back thereof to hold parts I!) and I3 together. By thismeans the hinge bar M of the loop-like hasp member 16 is pivotallyanchored at'the front or rounded closed end I! of a bearing notch in theside walls of housing l0, being yieldingly pressed thereagainst bya leafspring l9 which issecured by small rivets 2| to the mount ing plat I3.The latter is adapted, to be fastened, as by larger rivets 20, to thefrontwall of a container lid l2 which may be hinged in usual manner (notherein shown) to a container body whose front wall is shown at H. Hingebar I4 is provided with a flatted portion 24 separated from the arms l50f the hasp by rounded journal forming portions 25.

The flatted portion cooperates with spring H) to urge the hasp intoeither of its positions shown in Figs. 2 or 5, while the roundedportions afford a-- bearing fit for the hinge bar l4 within the roundedends l'lofthe bearing notch. Mounting plate [3 is shaped to provide theusual dowel tongue 22 which projects downward beyond the housing Ill andbeyond that edge of the container lid wall which abuts against thecontainer body wall.
